And those who are taken in death among you and leave wives behind - they, [the wives, shall] wait four months and ten [days]. And when they have fulfilled their term, then there is no blame upon you for what they do with themselves in an acceptable manner.1 And Allāh is [fully] Aware of what you do.
When someone passes away and leaves behind a wife who is not pregnant, it is the duty of such a woman to wait for a period of four months and ten days, in which she must not leave the husband’s home, beautify herself or get married. Once this period ends, there is no blame on their guardians if these women do these actions, which were previously prohibited during the waiting period, as long as it is done in a manner acceptable to society and the sacred law. Allah is well aware of what you do. None of your private or public actions are concealed from Him; and He will reward you for them.
